Transparent nanomeshes for smart windows

2021
Reports

Abstract

Conventional selective low-e coatings for windows of residential buildings have a cut-off frequency in the near infrared spectral region NIR, limiting the resulting solar heat gain coefficient to g ≈ 0.5. By structuring the coating into nanomeshes, the selectivity shall be enhanced, and higher solar heat gains shall be achieved. The resulting increase in solar heat gains will lead to energy savings in heating in the residential sector. In addition to this, metal nanomeshes will also allow to replace the transparent conductive oxide layer in electrochromic windows, reducing the needs for indium, and leading to higher switching speed and switching homogeneity.

Solar thermal energy

Solar thermal energy (STE) is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in industry, and in the residential and commercial sectors. Solar thermal collectors are classified by the United States Energy Information Administration as low-, medium-, or high-temperature collectors. Low-temperature collectors are generally unglazed and used to heat swimming pools or to heat ventilation air. Medium-temperature collectors are also usually flat plates but are used for heating water or air for residential and commercial use.

Passive solar building design

In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices. The key to designing a passive solar building is to best take advantage of the local climate performing an accurate site analysis.

Solar water heating

Solar water heating (SWH) is heating water by sunlight, using a solar thermal collector. A variety of configurations are available at varying cost to provide solutions in different climates and latitudes. SWHs are widely used for residential and some industrial applications (For example: in Israel). A Sun-facing collector heats a working fluid that passes into a storage system for later use. SWH are active (pumped) and passive (convection-driven). They use water only, or both water and a working fluid.
